Description
The portion of the electromagnetic spectrum with wavelengths ranging from 380 - 770 nanometers (nm). Visible radiation falls between ultraviolet and infrared regions of the spectrum. The shortest visible light waves are violet and the longest are red. The effects of radiation are measured in terms of its quality (color), quantity (intensity) and duration (time). Isaac Newton first used the word spectrum in 1671 to described the colors of light dispersed by a glass Prism.
